Genomic Variation Underpins Genetic Divergence and Differing Salt Resilience in Sesbania bispinosa

Advanced Science, EarlyView.
Sesbania, a leguminous halophyte, thrives in saline soils. Comparative genomics reveals key genomic variations—particularly chromosomal inversions—are identified as contributors to population differentiation and salt resilience. These findings advance the understanding of genomic variation driving evolution and phenotypic differentiation and offer ...

Tau Amyloid Corona‐Shelled Nanoparticle‐Based Drug Screening Platform for Discovering Tau Oligomer‐Degrading Drugs

Aggregate, EarlyView.
Tau amyloid corona‐shelled nanoparticles (TACONs) were synthesized by incubating gold nanoparticles (AuNPs) with tau monomers that had been pre‐reacted with heparin. These TACONs represent a promising high‐throughput screening platform for identifying tau oligomer degraders as potential therapeutic agents for Alzheimer's disease.

Simulations of the merging galaxy cluster Abell 3376 [PDF]

, 2013
Observed galaxy clusters often exhibit X-ray morphologies suggestive of recent interaction with an infalling subcluster. Abell 3376 is a nearby (z=0.046) massive galaxy cluster whose bullet-shaped X-ray emission indicates that it may have undergone a ...

Usage of the term provenance in LIS literature: An Annual Review of Information Science and Technology (ARIST) paper

Journal of the Association for Information Science and Technology, EarlyView.
Abstract Provenance is the story of how something has come to be. In this paper, we provide a systematic literature review to categorize the various notions of provenance in Information Sciences. The goal of this review is to paint a broader picture of the multiple uses of provenance at play and to enhance our understanding of the importance of ...
